Description

Technical Field

[0001] This application relates to the field of IR furnace technology, and in particular to an IR furnace feeding mechanism and an IR furnace. Background Technology

[0002] Fabricating layered functional structures using substrates is a key process encompassing multiple technological fields. Substrates not only provide the fundamental support load for these structures, but their unique material properties also facilitate their design, fabrication, and production. In most cases, heat treatment is required in the fabrication of layered functional structures using substrates. For example, conductive layers fabricated on ceramic substrates require a sintering process to sinter the conductive paste into a dense conductive film; while fabricating metal films requires an annealing process to eliminate stress generated during film formation and increase the adhesion between the film and the substrate.

[0003] The methods and equipment for heating substrates with layered functional structures are mainly related to the type and tolerance of the substrate, as well as the material and process requirements of the layered functional structure. These methods include resistance heating, laser heating, microwave heating, and heat conduction heating. The equipment includes heating tables, hot air equipment, reflow ovens, and microwave sintering furnaces. Among these, heating furnaces, as a mature technology, come in various forms, from simple box furnaces to multi-temperature zone reflow ovens, and have become one of the foundations of modern processing equipment.

[0004] In current heating furnaces, when heat treatment is performed on substrates used to fabricate layered functional structures, a specific piece of equipment can often only be used for one type and size of substrate. This results in the inability to support the heating of layered functional structures using substrates of different sizes, or the need to configure multiple heating furnaces to heat substrates of different sizes, leading to higher heat treatment costs.

[0028] The preferred embodiments of this application will now be described in detail with reference to the accompanying drawings, so that the advantages and features of this application can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of this application.

[0029] It should be noted that the terms "first," "second," and "third" in the claims and description of this application are used only to distinguish similar objects and should not be construed as describing a specific order or sequence.

[0030] Figure 1 This is a top view of the feeding mechanism in a specific embodiment of this application. Figure 1 As shown, in a specific embodiment of this application, an IR furnace is used as the main body of the heating furnace. An IR furnace is a high-efficiency and energy-saving heat treatment device that uses infrared radiation for heating. Its features include direct energy transfer and non-contact heating characteristics during heating.

[0031] Direct energy transfer refers to the IR furnace's ability to irradiate the target surface with infrared radiation through heating elements, converting it into internal energy to heat the target from the inside out. Compared to traditional convection heating, this method offers higher thermal efficiency, faster temperature rise, and more concentrated energy. The non-contact heating characteristic ensures that the heating chamber within the furnace retains sufficient space, allowing for the heating of a larger substrate 4 (the target object to be supported) within the same volume chamber, thus improving heating efficiency.

[0032] Specifically, in one embodiment of this application, the heating element used inside the IR furnace cavity can be a resistance wire, an infrared lamp, a quartz tube, etc., selected according to the required heating power.

[0033] Figure 2 This diagram illustrates a specific embodiment of the present application where the pull plate 1 and the cavity are engaged and closed. Figure 3 A schematic diagram shows the opening of the cavity by sliding the pull plate 1 out of the cavity; as shown Figure 2 , Figure 3 As shown, the feeding mechanism in this application can slide in and out of the cavity of the IR furnace via the pull plate 1. The pull plate 1 is adapted to the feeding port on the side of the cavity. When the feeding mechanism is fully inserted into the cavity, the pull plate 1 can be tightly fitted with the feeding port on the side of the cavity, thereby closing the cavity of the IR furnace. At the same time, in this state, the IR furnace heating can seal the heat inside the cavity. Firstly, it can utilize the heating heat more efficiently and avoid heat loss and waste. Secondly, it reduces the temperature impact on the outside of the IR furnace equipment and improves the overall safety performance of the equipment.

[0034] The layered structure requires substrate 4 for support because it exists in a non-fixed form before heat treatment. Taking the annealing and crystallization process of perovskite materials as an example, on the one hand, the perovskite layer exists in a solution state before annealing; on the other hand, considering the final product obtained after the process, the required micron-thickness, square meter-level perovskite active layer is extremely fragile and cannot be supported by itself. It must be supported by a rigid substrate to ensure its structural integrity. From the perspective of the preparation process, to obtain a uniformly thick, thin-film, square meter-level perovskite active layer, the perovskite solution needs to be evenly coated onto a flat and smooth substrate using processes such as spin coating or blade coating. Only in this way can the performance of the final product be guaranteed to be qualified. Therefore, the importance of substrate 4, which supports the perovskite layer during the overall heating process, is also determined.

[0035] Different sizes of substrate 4 have different uses. For example, in the research and development stage of perovskite crystallization, small-sized substrate 4 is usually used to develop and combine more materials because it has lower manufacturing costs and can quickly verify feasibility. When optimizing parameters in spin coating and annealing processes, medium-sized substrate 4 such as 20mm*2mm or 50mm*50mm can usually be selected. In actual production, to solve the problem of large-scale preparation, it is necessary to simulate real production conditions and use larger production-sized substrate 4 such as 100mm*100mm, 300mm*300mm, or 300mm*400mm.

[0036] Furthermore, the size range of substrates 4 used in actual production varies depending on the specific application requirements and environment. However, the substrate 4 sizes that can be applied to commonly available IR furnaces or other infrared annealing equipment are fixed. Different IR furnaces must be used for different sizes of substrates 4, which causes inconvenience in processing and increases equipment costs.

[0037] Figure 4 This is a schematic diagram of the present invention with respect to a substrate 4 with dimensions of 300mm*400mm in the first direction. Figure 5 This is a schematic diagram of the present invention regarding a 300mm*300mm substrate 4 in the first direction. Figure 4 , Figure 5As shown, this application provides a support bar 2, one end of which is fixedly mounted on the side of the pull plate 1 facing the cavity feed port. This side becomes one side of the IR furnace cavity when the pull plate 1 and the feed port are tightly fitted together, thus closing the cavity of the IR furnace. By positioning the support bar 2 towards the cavity feed port, it is ensured that the support bar 2 can penetrate into the interior of the IR furnace cavity at least when the cavity is closed, thereby fully approaching and utilizing the heat emitted by the heating element inside the IR furnace cavity.

[0038] In addition, the support bar 2 is set in a direction parallel to the horizontal plane. The function of the support bar 2 is to support other feeding components and the substrate 4 on the feeding components. Setting it parallel to the horizontal plane not only allows other feeding components on it to be set parallel to the horizontal plane, thereby achieving an even distribution of gravity, but also allows the substrate 4 supported on the support bar 2 to be coated with a layered structure solution, which can prevent the layered structure solution from flowing under the action of gravity and causing quality problems such as uneven product thickness.

[0039] The adjustable bracket 3 is horizontally mounted on the support bar 2. It should be noted that the adjustable bracket 3 includes a fixture bar 31 and multiple support blocks 32, both of which are parallel to the horizontal plane. The adjustable bracket 3 is a component mounted on the support bar 2 to provide load support for the target object, i.e., the substrate 4, during the annealing process in the IR furnace. The fixture bar 31 in the component has mounting positions for multiple support blocks 32. These multiple support blocks 32 form multiple fulcrums for supporting the target object. Since all support blocks 32 are identical and mounted on the same horizontal plane, the resulting support surface remains parallel to the horizontal plane, further ensuring horizontal support for the target object.

[0040] The fixture strip 31 includes a first fixture strip 311, which has multiple mounting positions for support blocks 32 along a first direction. By adjusting the mounting positions of the support blocks 32 along the first direction, the spacing between the support blocks 32 in the first direction can be controlled. Multiple first fixture strips 311 can be provided. By adjusting the mounting positions of the support blocks 32 along the first direction, support blocks 32 can be installed at different positions along the first direction. The support blocks 32 installed at different positions can be combined to support substrates 4 of different sizes along the first direction.

[0041] The reason for controlling the installation of the support block 32 in different positions by adjusting the installation position in the first direction, instead of installing the support block 32 in a movable installation method such as sliding or rolling in the first direction, is that: the connection relationship is more stable, the installation accuracy is higher, and the mechanical structure is simpler and more reliable.

[0042] In one specific embodiment of this application, in practice, the substrate 4 is mostly a standard rectangular shape, and the relevant dimensions of the substrate 4 are measured. The mounting spacing of the two support blocks 32 in the first direction of the first fixture strip 311 is determined by measuring the length or width of the substrate 4. In the two first fixture strips 311, the mounting positions of the two support blocks 32 are found by taking half of the measured dimensions of the substrate 4 in the first direction and the opposite direction of the first fixture strip 311, respectively, from the midpoint of the first fixture strip 311.

[0043] Since the first fixture strip 311 can be easily set at the center of the cavity near the IR furnace via the support strip 2, the centering method with the midpoint of the first fixture strip 311 as the midpoint makes it easier to keep the substrate 4 in the heating center area of ​​the cavity.

[0044] Furthermore, since each support block 32 is theoretically considered as a fulcrum of the substrate 4, three support blocks 32 that are not on the same straight line can determine a support surface for supporting the substrate 4. In practice, the substrate 4 is mostly a regular rectangular shape. By measuring the length or width of the substrate 4 and selecting the corresponding mounting position on the first fixture strip 311 to install multiple support blocks 32, the load support for substrates 4 of different sizes can be completed.

[0045] Figure 6 This illustration shows a schematic diagram of a feeding mechanism supporting substrates 4 of different sizes along a first direction and a second direction in a specific embodiment of this application. The jig strip 31 also includes a second jig strip 312, which is also provided with mounting positions for multiple support blocks 32. The second jig strip 312 can be a jig with the same or different size and specifications as the first jig strip 311. When the second jig strip 312 and the first jig strip 311 have the same size and specifications, the second jig strip 312 and the first jig strip 311 can be substituted for each other during use, thereby improving the uniformity of the overall equipment parts.

[0046] The second fixture strip 312 has a plurality of support blocks 32 arranged along the second direction. The installation position of the support blocks 32 in the second direction can be adjusted by controlling the second fixture strip 312, thereby simultaneously supporting substrates 4 of different sizes along the first direction and the second direction.

[0047] Meanwhile, based on actual production experience, the first direction is perpendicular to the second direction in this application. The reason is that, as mentioned above, the actual substrate 4 is mostly rectangular. The perpendicularity of the first direction to the second direction ensures that when the support blocks 32 are set along the first direction and the second direction, the multiple support blocks 32 set in the first fixture strip 311 and the multiple support blocks 32 set in the second fixture strip 312 can form a visually rectangular frame, thereby achieving accurate support for the substrate 4.

[0048] In one specific embodiment of this application, the first jig strip 311 has multiple mounting positions for the second jig strips 312 in a first direction, and the position of the support block 32 on the second jig strip 312 is adjusted by adjusting the mounting positions of the second jig strips 312 in the first direction through the first jig strip 311.

[0049] In general, the second fixture strip 312 can be installed and adjusted along the first direction according to multiple installation positions. By setting the second fixture strip 312 on the first fixture strip 311 for adjustment, the second fixture strip 312 replaces the support block 32 for adjustment along the first direction. The multiple support blocks 32 can be directly adjusted and installed at different installation positions on the multiple second fixture strips 312 to support the substrate 4 of any size rectangle within the installation position distance of the first fixture strip 311 and the second fixture strip 312.

[0050] Specifically, the dimensions of the substrate 4 to be supported are measured to obtain the length / width in the first direction and the width / length in the second direction. The position of the second fixture strip 312 on the first fixture strip 311 is adjusted according to the length / width. Preferably, the installation position of the second fixture strip 312 is determined by taking half of the measured length / width in the first direction and the opposite direction from the midpoint of the first fixture strip 311, so that the second fixture strip 312 is centered and installed on the first fixture strip 311.

[0051] Similarly, based on the measured width / length in the second direction, half of the measured width / length is taken from the midpoint of the second fixture strip 312 in the second direction and in the opposite direction to the second direction, respectively, to determine the installation position of the support block 32 on the second fixture strip 312, so that the multiple support blocks 32 installed on the multiple second fixture strips 312 are located at the center position of the first fixture strip 311 and the second fixture strip 312.

[0052] In one specific embodiment of this application, the support block 32 and the second fixture strip 312 have the same installation interface. With this arrangement, the support block 32 and the second fixture strip 312 can share the same installation position.

[0053] Specific principle: As described in the above embodiment, the adjustment and installation of the second fixture strip 312 and the support block 32 work together to achieve a more precise support effect for the base plate 4. The installation positions of the support block 32 and the second fixture strip 312 can be shared. This shared technical feature allows for the addition of multiple adjustment and installation positions without increasing their number. Compared to using separate installation positions, which requires more connecting structures, this embodiment not only reduces construction costs but also stabilizes the mechanical properties of the first fixture strip 311 by reducing the processing required.

[0054] Specifically, the connection method described here refers only to the mechanical fixing interface. The specific type of interface can be, for example, a standard threaded connection. The support block 32 and the second fixture strip 312 are equipped with fastening bolts of the same type, and the mounting positions of the support block 32 and the second fixture strip 312 have threaded holes compatible with these bolts. Considering that the support block 32 and the second fixture strip 312 may require frequent adjustments to their mounting positions under certain operational requirements, a guide rail can also be used for mounting. The guide rail is equipped with clips to securely connect with the support block 32 and the second fixture strip 312, making disassembly and adjustment more convenient.

[0055] In one specific embodiment of this application, the mounting positions of the support block 32 or the second fixture strip 312 are arranged uniformly along the first and second directions at fixed intervals. This allows for the setting of as many mounting positions as possible within a specified location at the required intervals, thereby improving the adjustment and installation accuracy of the support block 32 and the second fixture strip 312.

[0056] In one specific embodiment of this application, the installation positions of the support block 32 or the second fixture strip 312 are marked with graduations. The graduations are taken from the center of the first fixture strip 311 and the second fixture strip 312, with the first fixture strip 311 marked along a first direction and the opposite direction, and the second fixture strip 312 marked along a second direction and the opposite direction. These markings allow for quick determination of the required adjustment and installation positions of the support block 32 or the second fixture strip 312 on the first fixture strip 311 and the second fixture strip 312, improving work efficiency.

[0057] Figure 7A schematic diagram of a support slot 33 in a specific embodiment of this application is shown. The support block 32 achieves positioning by supporting the substrate 4 through the support slot 33. The support slot 33 mainly positions the four corners of the rectangular substrate 4. The support slot 33 includes two straight sections 331, which are perpendicular to each other to form a slot. The two straight sections 331 that form the slot are respectively positioned close to the two right angles of one corner of the substrate 4 for positioning. The two straight sections 331 are connected by the two ends of a curved section 332. The curved section 332 is formed by a curve that bends away from the slot when projected on the horizontal plane. By setting the bending direction, the curved section 332 can maintain a certain distance from the corner of the positioned substrate 4, that is, maintain a non-contact state.

[0058] This is because, based on commonly used material selection criteria, glass is a relatively ideal material for substrate 4, specifically glass coated with transparent conductive oxide (TCO) (such as ITO glass or FTO glass). Firstly, glass has excellent light transmittance, which is essential for layered structures primarily used in solar energy materials and optical devices. Secondly, glass has high surface flatness and smoothness, providing conditions for preparing uniform, pinhole-free layered structures. Thirdly, glass has excellent high-temperature resistance and dimensional stability, thus providing a stable heating platform during the annealing process.

[0059] However, the corners of the glass are among the most stress-concentrated areas in the entire substrate 4. According to Hertzian contact stress theory, point or line contact will generate enormous pressure. In addition, glass itself is a brittle material. When direct contact with a corner generates stress exceeding the strength limit of substrate 4, substrate 4 will break directly. The design of the bending portion 332 avoids this problem, thereby improving the support safety of substrate 4 during installation.

[0060] Figure 8 This is a schematic diagram of a specific embodiment of the pull plate 1 and cylinder 101 in this application, wherein... Figure 9 for Figure 8 A schematic diagram of the side view of the pull plate 1 and the cylinder 101 in a specific embodiment. According to... Figure 8 , Figure 9 As shown, multiple cylinders 101 are symmetrically arranged on the pull plate 1. The arrangement of multiple cylinders 101 ensures that the cylinders 101 have sufficient driving force. The symmetrical arrangement of them on the pull plate 1 makes the driving force of the cylinders 101 act on the pull plate 1 more evenly, so that the speed of the pull plate 1 is more stable when it slides in and out of the IR furnace cavity.

[0061] Preferably, the cylinder 101 mounted on the pull plate 1 has a pilot-operated speed control connector. This pilot-operated speed control cylinder has a rotary adjustment knob that can adjust the opening of the throttle orifice of the cylinder 101, thereby precisely controlling the cylinder speed. The solenoid valve assembly of the cylinder 101 is a three-position, five-way, center-sealed solenoid valve, which can control the direction of movement of the cylinder 101. Furthermore, it can lock the cylinder piston at its current position through a specific port connection method. The cylinder 101, equipped with a pilot-operated speed control connector and a three-position, five-way, center-sealed solenoid valve, can achieve bidirectional controllable speed regulation and precise stopping at intermediate positions.

[0062] Figure 10 This diagram illustrates a specific embodiment of the pull plate 1 with a pull door 102. In another specific embodiment, a pull door 102 is added to the pull plate 1. The pull door 102 is fixed to the pull plate 1 by a fixing plate 1021 located near the feed port. The pull door 102 can be manually driven to slide the pull plate 1 relative to the IR furnace cavity. The fixing plate 1021 is directly fixed to the pull plate 1. To ensure good sealing of the IR furnace cavity when the pull plate 1 and the pull door 102 are installed together, a sealing strip is provided between the fixing plate 1021 and the pull plate 1. The sealing strip ensures the sealing of the connection between the pull door 102 and the pull plate 1, thereby further ensuring the sealing of the pull plate 1 when it is in contact with the IR furnace cavity. Considering the operating environment of the sealing strip, a heat-resistant sealing strip is preferred.

[0063] In one specific embodiment of this application, the sliding door 102 has a cavity inside which a heat-resistant material 1022 can be filled, and a heat insulation plate 1023 is provided between the sliding door 102 and the fixed plate 1021. It is known that the fixed plate 1021 is in direct contact with the cavity of the IR furnace, allowing heat from inside the IR furnace cavity to be directly transferred to the sliding plate 1 and the sliding door 102. Since using the sliding door 102 requires direct human contact, heat insulation is applied to the sliding door 102 to prevent burns and other accidents. The heat insulation plate 1023 is made of PTFE material to insulate against heat transmitted from the fixed plate 1021. The heat-resistant material 1022 filling the sliding door 102 is aluminum silicate insulation cotton, further isolating heat conducted through the heat insulation plate 1023 and heat conducted from the sliding plate 1 to the sliding door 102.

[0064] Preferably, a groove is provided on the pull plate 1, and the pull door 102 is set in the groove of the pull plate 1, thus forming a hidden pull door structure, which improves the overall aesthetics of the IR furnace.
